TRUMAN DURNBAUGH, OF WAIBASH, INDIANA.

lb iz'lkwhom it may concern:

{Bait known that I, TRUMAN DURNBAUGH, a citizen of the United States,residing at Wabash, in the county of Wabash and State 51 i Indiana,haveinvented certain new and useful-Improvements in Dust-Catchers for'Gas Pipes; and I.do declare the following to be a full,."clear, and.exact description of theinvention, reference being had totheaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a art of this specification.

This invention relates to devices for trapping-and holding sedimentaryor other matter that may be present. in pipes through c which fluid orliquid may be conducted, the invention having reference moreparticularly to a device for catching and retaining rust, scale or dustin gas-pipes. v

The object of the invention is to provide a neatappearing and cheaplyconstructed trap or-du'st catcher of the above-mentioned character thatwill be effective in preventing dust or similar Lmatter, especially ingas-pipes, from entering connecting valves or feed Y tubes or burnersoflamps connected with the pipes; a further object being. to provide animproved dust catcher by the use of which trouble'and expense, resultingfrom the dust or rust falling from the-walls of the pipes into thevalves, may be avoided in an economical manner and which permits readyremoval-of the dust that; may accumulate,

and thereby eliminates expenses-for repairs '35., for disconnectingthepipes to clear them.

With:thegabove mentioned and other objectsin-view, the inventionconsistsin an im proved gravity trap comprising aseparati'ng box havinga reservoir andflp'rovided with a 40 deflector for deflecting the dustor other foreign matter into the reservoir, and'providedalso with abarrier to'arrest particles of the matter that may bedrawn' by theflowing'gas partially into its channels, the gas channel in theseparating box being circuitous. v The invention consists further in theparts and combinationsand arrangements of parts as hereinafterparticularly described and 5 then defined in the appendedclaims.

Referring-to the drawings Figure 1 is an elevation -of'the improved dustcatcher in connection with a drop pipe and the dual gas lamp, the latterbeing indicated by 'broken-lines as illustrative of one ofthe'applications of the invention for practicalpur- Specification ofLetters Patent.

poses; Fig. 2, a vertical section of the dust catcher on the line A A inFig. 1; Fig. 3, a horizontal section approximately on the line BB inFig. 2; Fig. 4, a' fragmentary vertical sectionon theplane of the line CC in Fig. :2; and Fig. 5, a side elevation of the improved dust catcher.

Similar reference characters in the several figures of the drawingsindicate like parts or features of construction herein referred to.

The improved dust catcher is illustrated and usually used in'connectionwith substantially vertical pipes, but it is-apparent. that it may beused in other than verticalposition, and it comprises a se arating boxprefat vertical sides a and a andcurved ends I; and c, theiend b i beingsubstantially straight vertically. =and the end 0 mainly straightvertically and having a curved upper portion 0. extendingiover towardthe end (I, so as to form a top for the box from which a flange extendsupward and joins the end 6 to constitute a neckjcl suitably adapted tobe connected to a pi e 6 through which gas may be conducted into theupper portion of the separating box.

The separating box has a bottom part 1 at the middle portion of thelower ends of the sides (tor a and a nipple g extending downward fromthe bottom, being formed partially thereon-and partially as an extensionof the end 6 to provide an outlet for the gas from the separating box,the nipple being adaptedto have a valvebody h suitably con'nectedthereto as by means of a pipe'cou-I pling 2', it being desirableto arrange the valve .for controlling the flow ofthe gas near to theseparating box, thevalve-body it havin a rotary valve plug j therein provided with an. operating handle-bar. k to which operatingchains Z and Zare connected as is customary,'the plug having a passageway mthereinthrough which the gas may flow, a pipe at being .connectedto thealve-body h to receive and conduct thegas.

The pipe a may be apart of a gas lamp and have horizontal feed-pipes oand 0' connected thereto that have upright branches 1) and grespectively on which are mounted lamp urners g and g, respectively.

The upper portion of the separating box is provided with a deflector 1*that extends from the end 6 along the inner sideof the sides a and atbelow the neck I) and toward the end a, the deflector having an inclinedupper side r that slopes downward toward .FFIC.

load "carried. on each rn power from the s of 'thegwheel to thewheel.;,,. It is found that in order to obtain f suificient resiliencyin ,gdepiend for their resiliency only upon the use ofa rubber orpneumatic tire the tire must-if be of large diameter and therefore ofconsiderable weight in zfioroes coming upon it;

liye it known that I, ROBERT T. EVANS, a citizen of the United States,residing at Chicago, in the county of Cook and State I b fof Illinois,have invented certain new and ,nseful Improvements in, Resilient Wheels.ifor vehicles,

; specification.

of which the following is a hi'sainvention relates to resilient wheelsintended more particularly for use on automobiles and similar vehiclesin which the wheel is relatively it is necessary to translar e, and inwhich axle or central portion pavement through the y solid wheels whichorder to sustain the and it is further -.found that the use of rubbertires of large 1 diameter greatly increases the skidding tendency o thewheel, by reason of the fact' I that it flattens out when it-comes incontact. with the pavement and retains a thin film 'of slippery materialor moist re under it.

An object of this invention is to provide a resilient wheelwhich willobviate the necessity of using a pneumatic or similar "cushion tire oflarge diameter, but in no ;-way impairing the smooth riding qualitiesordinarily obtainedby the use of pneumatic I or similar tires.

A further object of the invention is to ,provide a wheel which willrequire no lubrication or. attention of any sort, and one which may beused as-thedriving'wheel of I the vvehicle, whether itbe chain or shaftdriven.

Another object is to provide a wheel w i'ch when used as a driver willabsorb fall shockdue to change of speed of the motor'or engine of thevehicle, or to the application of'the brakes of the vehicle, also toprovide a wheel which may be used on the standard form of axle,ordinarily used in vehicles of this type.

My 'improved wheel is provided with springs so: positioned within itthat thew variousshocks-and strains coming upon the ywheejl, whetherfrom encountering obstacles in the pavement or due to changes in thespeed of the driving mechanism, or due to application of the brakes,will beabsorbed y the springs, on account of the peculiar manner inwhich they are arranged in the wfheel. and attached to the-solidportions it. I

Further objects will appear from a detailed description of theinvention, which consists in the features of construction andcombination and claimed. In the drawings, Figure 1 is a sideelevation ofa portion of my improved wheel, showing the side plate cut awayat onepoint to expose one of the springs beneath it; Fig. 2', asectionalelevation of the wheel; Fig. 3, a detail of one of the blocks forattachin the springs solidly to the rim and hub o the wheel, showing thespring attached to it; Fig. 4, a plan view of one-of theseattachingblocks, and Fig. 5, a detail of one of the ,blocks, the block beinginverted from the position shown in Fig. 3 and rotated through an angleof 180. H Y

The wheel has an outer-rim -6, preferahly formed of wood, and having ametal band 7 shrunk on its periphery, the band being provided with arecess for receiving a solid rubber tire 8, preferably of smalldiameter. The rim 6 is attached to an'innerrim'9,'also preferably ofwood, by means of spokes 10 having on their ends pegs 11 for holdingthem securely to the rims 6 and 9. It is seen that the inner and outerrims, withthe spokes, metal band, and tire, constituteone member of thewheel,which is rigidand practically unyielding in itself.

A solid metal hub 12 can be attached to a shaft or journaled on the endof a shaft,rde-

pending upon whether the wheel is to be driven or driven in any othersuitable shaft manner. A flange 13, integrally formed with the hub 12,constitutes a shoulder against which abut filler blocks 14 and 15 ofwood or any other suitable material. A cir-.

cular metal band 16 encircles the filler blocks, and is of such widththat it comes flush with the outer edges of the filler blocks.

The band 16 is attached to the outer portion of the Wheel by means. ofhelical springs 17 solidly attached to the band at pneend and to theinner rim at the other end. The method of solid attachment to thebandand a grinding the feculawith potable ,water, ex

aniliar with any form of springs are so attached to the rim and to theplates 18 and 19 enables the springs to be protected from dirt and dustand at the same time serves to guide the upper rim portion of the wheelin its vibrations back and forth with respect to the hub portion. Also,in case of extreme movements, any possible deflection of the springsmight be resisted by their coming in contact with the side plates.

Although I am familiar with resilient wheels in which use is made ofsprings for accomplishing resiliency, still I am not fawheel in whichthe band-that they will be given the strength which it is evident mysprings will possess, by reason of the peculiar manner in which I attachthem. The necessity for their being properly attached in their endportions willbe readily appreciated by any one familiar with thestresses coming upon wheels used in automobile or similar'services, inwhich not only the jarring and jolting occasioned by passing overobstacles is encountered, but also in which the torsional forcesoccasioned by application of power and the setv ting of brakes areencountere I claim In a resilient wheel for vehicles, an inner the hub,a filler block on each side of the flange, a band surrounding the fillerblocks and the flange, and circular side plates attached to the fillerblocks and the flange and projecting beyond the band, and an outer rimportion comprising an'inner ring and an outer ring firmly attachedtogether, the inner ring movably contained between the circular sideplates, and the inner ring connected with the band which surrounds thefiller blocks and the flange, of radial springs,
